Rookie Blue is still showing some major signs of life.

The Canadian-produced cop drama, which aired its sixth season and possible series finale Thursday, jumped two-tenths to a 0.7 rating among adults 18-49.

The rise was even more impressive considering Rookie Blue followed the season finale of Mistresses (0.6 adults), which fell two-tenths. 

Big Brother (2.0 adults) still topped the night for CBS, which was steady thanks also to Under the Dome (0.8 adults).

NBC saw big dips for Food Fighters (0.5 adults) and Dateline Mystery (0.8 adults), which were down four-tenths and three-tenths, respectively.
